Oncidium floridanum?

[gixrj18]

This is one of the plants that were in the big collection that I bought from someone, last spring. The collection was mostly Florida native species. There were several untagged oncidiums in the bunch, and I did find a tag that said, "Onc. floridanum" lying loose in the load of about 100 plants. This one just opened it's first bloom, and it looks a lot like it. None of the other Oncidiums from the group are blooming, this is the only one. It has only been open for two days, so I imagine it will darken a little. So the question is, floridanum, or not?
